| comparative histomorphology of the mauthner cells in some freshwater teleosts. | the histomorphological observations are made on the mauthner cells in eight species of teleosts belonging to six different families. the cells are better developed in channa punctatus, heteropneustes fossilis, labeo rohita, danio, malabaricus and puntius ticto. they are symmetrically situated in nandus nandus and are found to be absent in mastocembalus armatus. their position, shape and size vary in different species. the axon cap is well developed in channa punctatus, heteropneustes fossilis an ... | 1975 | 1234388 |
| fungal diseases of fish in nanak sagar, naini tal, india. | eight zoosporic fungi viz., achlya debaryana, a. flagellata, a. klebsiana, aphanomyces laevis, saprolegnia diclina, s. ferax, s. parasitica, and pythium sp. were isolated from a large number of adult fishes of the species mastacembelus armatus, mystus vitatus, nandus nandus, tor putitora and t. tor of nanak sagar reservoir in naini tal district, india. species of the parasites and the hosts were different in their pathogenicity and immunity, respectively. however, a. flagellata and s. parasitica ... | 1995 | 7566059 |
| haematological investigations on fishes infested with fungal growth. | considerable changes have been observed in the haematological parameters of labeo rohita, mystus cavasius, nandus nandus and puntius sarana infested with aphanomyces sp., saprolegnia parasitica, achlya prolifera and dictyuchus monosporus, respectively. substantial decline have been observed in the number of erythrocytes and lymphocytes. the number of granulocytes and monocytes were noticed significantly increased. the amount of haemoglobin has also been decreased drastically in all the cases. | 2001 | 12018597 |
| a redescription of sundanonchus behuri (agrawal & singh, 1982) n. comb. (monogenoidea: dactylogyridea: sundanonchidae) from the gills of the freshwater gangetic leaffish, nandus nandus (perciformes: nandidae) in india. | urocleidus behuri [agrawal n., singh h.s., on a known and three unknown monogenetic urocleidus mueller, 1934. pranikee 1982; 3: 22-34], described from nandus nandus in india, is reassigned to sundanonchus lim & furtado [ lim l.h., furtado j.i., sundanonchus g.n. (monogenea, tetraonchoididae) from two malaysian freshwater fishes. fol parasitol 1985; 32: 11-19]. sundanonchus triradicatus lim & furtado [lim l.h., furtado j.i., sundanonchus g.n.

| studies on trichodinid and chilodonellid ciliophorans (protozoa: ciliophora) in the indian freshwater and estuarine fishes with description of trichodinella sunderbanensis sp. nov. and trichodina nandusi sp. nov. | a comprehensive icthyoparasotological survey among estuarine and freshwater fishes of west bengal, india revealed trichodinella sunderbanensis sp. nov. and trichodina acuta lom, 1961 from an estuarine fish mystus gulio (hamilton, 1822) from the vidyadhari river; trichodina nandusi sp. nov. from a freshwater fish, nandus nandus (hamilton-buchanan); chilodonella hexasticha (kiernik, 1909) kahl, 1931 from freshwater fishes labeo rohita (hamilton, 1822); and cyprinus carpio linnaeus, 1758 from the r ... | 2012 | 23269510 |
| histomorphological observations on the liver in some freshwater teleosts. | histomorphology of liver is studied in six species of teleost viz., heteropneustes fossilis, clarias batrachus, puntius ticto, danio malabaricus, nandus nandus, chana punctatus. the liver is a bilobed structure usually reddish brown in colour. there are accessory liver lobes in h. fossolis and c. batrachus. the histological examination shows compact mass of oval or polygonel hepatocytes, blood sinusoids and reticuloendothelial cells. in addition several patches of pigmented hepatocytes are also ... | 1975 | 1234395 |
| enhancement of reproductive performances of gangetic leaffish, nandus nandus through up regulation of serum ca²⁺ concentration, improved morphological alteration of liver and ovary with dietary polyunsaturated fatty acids. | incorporation of polyunsaturated fatty acids (pufas) as biofunctional compounds with feed is an effective way for gonadal maturation without any hazardous effects on animal health, and thus it is possible to save the vulnerable species from the danger of extinction. in the present study sperm quality, level of ca(2+) concentration in serum, histological structure of the liver and developmental stages of ovary of an endangered fish species, nandus nandus were investigated for the confirmation of ... | 2013 | 23108804 |
